[Signal Generator]: Built-in waveform signal generator, it can output , squarewave, trianglewave, and so on. The voltage amplitude is 2.5V, the frequency is adjustable from 0-2Mhz, and the squarewave duty cycle is adjustable from 1% to 99%. Features:[3In1 Design with IPS Display]: This product ingeniously integrates digital oscilloscope, multimeter, and signal generator functions into one device. 3.2-inch clear-definition IPS display, high sensitivity full view display, channel 2 waveforms can be set to green/ cyan/. [Digital Oscilloscope Function]: Dual channel oscilloscope function, with 120MHz bandwidth and 250MSa/s sampling rate. With perfect trigger function (automatic, single, normal). [High-precise Multimeter]: Built-in true RMS multimeter, that supports quick software calibration. With DC/ACvoltage, DC/ACcurrent, resistance, capacitance, diode, and continuity test. When measuring low voltage /resistance/continuity, the oscilloscope and multimeter functions can be used simultaneously (small window in the upper right corner). [Two Automatic Modes Adjustment]: Support one-button automatic and fully-automatic mode, no complicated operation, you can quickly detect and display the waveform. In fully automatic mode, no keystrokes are required, and continuous automation is performed., Manufacturer: Ounfhtrttk
